Two problems related to car will not start have been reported for the 2012 Jeep Wrangler. The most recently reported issues are listed below.
Driving home every light on my dash started blinking, no rpm, no speedometer. Blinkers did not work. When I turned into my driveway, parked and I turned the key but Jeep did not turn off. I was able to take my key out and the Jeep stayed running for a minute then turned off. Jeep would not restart.
12 jkru 52,000 miles. It first happened at night while wife was driving on interstate Jeep went crazy mode all lights in cluster illuminated warning lights flashing and with hot oil msg, warning dings going off, heard electric fan running . It seemed that nothing was controllable, auto trans went into and would not shift out of first gear. Scared the hell out of my wife. Got home after shut off I tried to restart but nothing happened. I disconnected battery to reset cpu that did not work. I stopped by auto zone to get codes scanned . They told me every system was reporting failure and needs to go to dealer. After restart every thing was normal. After 100 yards down the street it all happened again. Pulled into store parking lot, turned Jeep off and would not restart till 4th try. Drove it strait to dealer in first gear with all. They said that it was tipm and not under warranty, gave MA a rental car for 10 days because part is on back order. After 10 days Chrysler quit paying for rental car and still have no part to fix Jeep it has been 16 days. I guess there are alot of failures for the tipm causing back order and do not know when they will get one.
